Pre-Installation

This section provides the following pre-installation information:

• Location considerations

• Height requirements

• Mounting surfaces

• Maximum wire length

Location Considerations

When selecting a location, avoid the following:

• Areas of direct sunlight

• Areas in the direct airstream of air diffusers

• Exterior walls and other walls that have a temperature differential between the two sides

• Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys, or other heat-generating equipment

• Drafty areas

• Dead spots behind doors, projection screens, or corners

• Walls that are subject to high vibration

• Areas with high humidity

• High traffic areas (to reduce accidental damage or tampering)

Height Requirements

It is recommended that you mount the back plate a maximum distance of 54 in. (137 cm) above the floor. If a parallel approach by a person in a wheelchair is required, reduce the maximum height to 48 inches.

Note: Consult section 4.27.3 of the 2002Americans with DisabilityAct guideline, and local building

codes, for further details regarding wheelchair requirements.

Mounting Surfaces

The thermostat can be mounted to any sturdy, vertical surface. Plastic threaded anchors and

M3.5 x 20 mm screws are provided for mounting to plaster or wallboard; 6-32 x 3/4 inch machine screws are provided for mounting directly to a standard electrical device box. Other fastener varieties may be required for other surface types.

When replacing a horizontally mounted thermostat and there is an adapter kit available to cover

any opening in the wall. Contact your localTrane office for more information.

10 BAS-SVX36C-EN

Pre-Installation

Maximum Wire Lengths

Thermostat to HVAC Equipment

The thermostat may not function properly if the total resistance of any of the thermostat to HVAC

equipment wires exceeds 2.5 ohms.To ensure that wire length does not cause excess resistance, refer to Table 1 and ensure that the wires from the thermostat to the HVAC equipment are not too long.

Remote Sensor to Programmable Thermostat

Because remote temperature sensors measure resistance, very long cable runs can cause slight errors in the measurement. For the highest temperature reading accuracy, avoid exceeding the maximum recommended wire lengths shown in Table 2.

Note: For 22 AWG (0.33 mm2) copper wires, the rate of error can be up to 0.5 °F (0.3 °C) per 100 ,

which typically requires wire lengths in excess of 5000

ft (1500 m).

Table 1. Maximum Thermostat to HVAC Equipment Wire Lengths

Copper wire size Maximum recommended wire length

BAS-SVX36C-EN 11

Installation

This section provides installation instructions.

Before you begin, read through the pre-installation information, beginning on p. 9, and also verify the following conditions are met:

• A wire access hole is available at the thermostat location.

• The wires are accessible through the hole.

• The wires are attached to the appropriate terminals on the HVAC equipment.

• There is continuity (and not more than 2.5 ohms resistance) between the thermostat location and

the HVAC equipment.

• The wires are accurately labeled or identified by color.

Mounting the Back Plate

WARNING

Hazardous voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

NOTICE

Equipment damage!

Applying excessive voltage to the thermostat will permanently damage it.

To mount the back plate:

1. Shut off power to the HVAC equipment.

Note: If

the security screw is installed, remove it before attempting to remove the cover.

See Figure 3.

Figure 3.

Security screw

Security Screw Location (if used)

2. Remove the cover by firmly pressing the thumb tab at the bottom of the cover and pulling the co

ver away from the back plate.

3. Feed the wires through the opening in the back plate.

12 BAS-SVX36C-EN

Installation

Figure 4. Feeding Wires through Back Plate

4. If you are mounting the back plate directly to a wall surface, hold the back plate against the surface and mark the fastener locations.

5. Secure the back plate using appropriate fasteners. (See “Mounting Surfaces,” p. 9.) The thermostat must be level and plumb for accurate temperature control and to ensure proper air mo

vement through the thermostat enclosure.

Wiring

WARNING

Hazardous voltage!

NOTICE

Equipment damage!

Applying excessive voltage to the thermostat will permanently damage it.

General Practice

To wire the thermostat:

1. Connect the wires to the terminal block(s) packaged in the box with the thermostat. (The programmable

thermostat has two terminal blocks, the non-programmable thermostats have

only one):

• R

emove approximately 1/4 inch (6 mm) of insulation from the wires.

• Use the terminal block screws to securely fasten each wire into the terminal block.

• Refer to the section, “Terminal Identification,” p. 13 and the wiring diagrams on the pages

that follow to determine the correct terminal for each wire.

Note: In

some cases the terminal labels (Y, G, R, etc.) correctly correspond to first letter of the color wire to which they are connected. However, you must verify which equipment terminals are connected at the other ends of the wires before connecting the wires to the thermostat.

BAS-SVX36C-EN 13

Installation

2. Align the pins on the circuit board with the holes onthe bottom of theterminal blocksand gently push the wired terminal blocks into place on the circuit board. See Figure 5.

Operation

Non-ProgrammableThermostats

Non-programmable thermostats do not have timekeeping or scheduling capabilities.They will continue to maintain heating and/or cooling setpoints until an operator makes changes to the setup.Therefore, only the following tasks may be required performed:

• Change the system mode.

• Show or change the heating or cooling temperature setpoint.

• Change the fan mode.

Note: The

system mode, temperature setpoints, and fan mode can each be individually locked to

prevent users from changing them. If you see a on the display, you may need to unlock

the setting before you change it (see “Locking or Unlocking Modes,” p. 40).

Changing the System Mode

Note: If you are unable to change the system mode, checkthe system type setting and the manual/

auto changeover setting (see “Configuration,” p. 26) to verify that the thermostat is configured with heat and cool modes, and that it permits manually changing them.

Depending upon the model and system type, the thermostat can be set to one of five modes: Cooling, Heating, Emergency Heat, Auto, or Off.

Note: The

1-Heat/1-Cool thermostat does not have Emergency Heat mode.

To change the system mode:

1. Press > .The current mode flashes.

2. Press or to select a mode.

3. Tap or wait 5 sec to save and exit.

Showing or Changing the Heating or Cooling Temperature Setpoint

To change the heating or cooling setpoint:

1. Press or once.This shows the active setpoint.

2. Within 5 sec:

• P

ress or to increase or decrease the setpoint.

• Press or to change between heat and cool setpoints if both are enabled.

3. Tap or wait 5 sec to save and exit.

Cooling mode cools the room to bring it down to the cooling setpoint.

Heating mode heats the room to bring it up to the heating setpoint.

Emergency Heat mode heats the room according to the heating unit’s emergency heat mode

settings.

Auto mode switches automatically between heating and cooling modes as required.

Off mode prevents the thermostat from requesting any heating or cooling regardless of the

room temperature. Off mode also disables fan selection and prevents the user from changing the setpoint.

BAS-SVX36C-EN 35

Operation

Changing the Fan Mode

Note: If you are unable to see the fan mode, check the system type setting in the installation

configuration options to make sure that it is specified as a system with a fan.

There are two fan modes. Each are indicated by an icon on the display:

o change the fan mode:

1. Press > > .The current mode flashes.

2. Press or to change the mode.The selected mode flashes.

Note: If

you are unable to change the mode and flashes, the mode is locked. See “Locking

or Unlocking Modes,” p. 40.

3. Tap or wait 5 sec to save and exit.

ProgrammableThermostats

Programmable thermostats contain all of the functionality of the non-programmable thermostats, but they also keep track of the date, day of week, and time of day for scheduling purposes.

Programming

This section describes how to program the thermostat after it has been installed and configured.

Setting the Time

The time must be set in the thermostat to ensure operation of the schedule.

Note: The

date is set during configuration and the day of the week is calculated automatically

according to the date.

To set the time:

1. Press > > > > > .The hour flashes to indicate that it can be changed.

Note: The thermostat automatically returns to normal operating mode if no buttons are

pressed for 10 sec.

2. Make changes to the hour and minute, as needed:

• P

ress or to switch between hours and minutes. The changeable option flashes to

indicate that it can be changed.

• Press or to change the value of the option.

3. Press and hold for 2 sec or wait 10 sec to apply the change and exit.

Auto mode turns the fan on and off as needed according to equipment configuration.

On runs the fan continuously.

36 BAS-SVX36C-EN

Operation

Scheduling

The thermostat can be configured for two periods (day and night) or four periods (morning, day,

evening, and night).The chosen number of periods are applied to each day of the week when you program the thermostat. Each period canhave a unique start time, heat setpoint, cool setpoint, and fan setting.

The groups of days can be one of the following:

• 1 day = all 7 days of the week follow the same schedule.

• 5+1+1 days = Monday - Friday all follow the same schedule; Saturday and Sunday each follow their own schedules.

• 5+2 days = Monday - Fridayall follow the same schedule; Saturday and Sunday follow the same schedule, which is different than the Monday - Friday schedule.

• 7 days = Each day follows its own schedule.

Note: See “Configuration,” p. 26 to change the number of periods in a day or the grouping of days

in the schedule.

If needed, you can use Table 9 to write down your schedule settings before you begin setting up the schedule.The default schedule is also shown in the table. Unless you program your own schedule settings, the thermostat follows the default schedule for all days of the week.

Operation

Day-to-Day Operation

After a programmable thermostat is configured and the schedule is programmed, the thermostat

automatically changes the setpoints and fan settings accordingto theschedule.However, there are some operator tasks that you may need or want to perform:

• Show setpoint or current temperature.You can temporarily or permanently switch the main display

from current temperature to temperature setpoint. See “Showing the Setpoint or

Temperature on Display,” p. 39.

• Set the system mode, which includes turning the system on or off, and switching between heating,

cooling, and automatic heating and cooling. See “Changing the System Mode,” p. 34.

• Override the schedule. If an unexpected, one-time temperature setpoint or fan mode change is needed

you can temporarily override the schedule. See “Timed Override (TOV) Mode,” p. 40.

• Lock or unlock. You can lock the thermostat buttons to prevent changes to the thermostat set

tings. See “Locking or Unlocking Modes,” p. 40.

Note: It

is possible for a programmable thermostat to be configured to be a non-programmable thermostat. If installation configuration option #140 is set to 0, schedule programming capabilities will be absent.

Showing the Setpoint or Temperature on Display

Depending upon the value of configuration option #210, the large numeric display could show any of the following:

Operational and Programming Reference Information

This section provides additional information that may be useful for understanding thermostat

operation or programming.

Deadband

The thermostat automatically maintains a temperature deadband between the heating setpoint

and the cooling setpoint whenever automatic changeover (heat-to-cool or cool-to-heat mode) is enabled.The temperature range of the deadband is 2–9 °F (1.0–4.5°C) and is specified in the installation configuration options (see “Configuration,” p. 26). If you attempt to change a temperature setpoint to within the deadband of its opposing setpoint, the opposing setpoint will automatically be pushed to the next value that satisfies the deadband. (See Figure 38.)

Heat and Cool Cycling Rate

The heat and cool cycling rate, expressed in cycles per hour (CPH) indicates how often heating or

cooling system is turned on when temperature is within the temperature differential from the setpoint, which is 1°F (0.5°C).There are ten options (1–10) for heat stages and five options (1–5) for cool stages.The number selected is the maximum number of times the stage is cycled in 1 hr.

For example, when the system is set to 5 CPH, it runs at 12 min cycles with variable duty cycle. Depending on the heating or cooling load, which is measured by feedback from the sensor thermistor and/or temperature error, the system could run at 50% duty cycle (6 min ON and 6 min OFF), 80% duty cycle (9.6 min ON and 2.4 min OFF), or other variations of the duty cycle.

Note: The

cycling rate described above is only active when the temperature is within the temperature differential. If the temperature is outside of the temperature, the heating and cooling equipment will either be fully on or fully off accordingly. (See Figure 38.)

Figure 38. General Heat and Cool Cycling Rate Diagram

There is one cycling rate setting for each of the thermostat’s available heat and cool stages,

including

auxiliary and emergency heat stages.You can specify them during installation

configuration. See “Configuration,” p. 26.

Minimum Compressor Off Time

To protect the compressor from cycling too frequently, there is an automatic 5 min gap between

cycles.You cannot reduce the gap, but you can add up to 5 min if needed. See “Configuration,”

p. 26.

Operational and Programming Reference Information

Configuration and Programming Retention

The thermostat retains the time and date for a minimum of 5 days with no electricity. If power is

lost for more than 5 days, you will need to reset the time and date when power is restored.

All configuration parameters, system settings, and scheduling are stored in non-volatile memory,

which will retain the data indefinitely with or without power.

Note: You can manually revert to default settings by setting the appropriate installation parameter

(#300 for programmable thermostats or #18 for non-programmable thermostats) to a value of 1, and exiting configuration mode.

Extended Fan-onTime (Heat or Cool)

Note: This feature applies only to the programmable thermostat.

When the thermostat fan is in Auto mode, the fan on time can be extended.

• Configuration option #270 extends the fan on time by 90 sec after heat turns off.

• Configuration option #271extends the fan on time by 40 sec after cool turns off.

These options may not be available for some system configurations. See “Configuration,” p. 26.

Compressor and Auxiliary Heat Lockout

Note: This feature applies only to the programmable thermostat.

Compressor and auxiliary heat is used for heat pump systems with more heat stages than cool stages. When the temperature from an outdoor sensor is

• above the auxiliary lockout point, only the compressor will operate on a call for heat.

• below the compressor lockout point, only the auxiliary heat will operate on a call for heat.

• between the compressor and auxiliary lockout point, the compressor and auxiliary heat will operate on a call for heat.

There is a minimum 5°F (2.5°C) deadband between compressor and auxiliary heat lockout

temperatures. Configuration option #220 sets the compressor lockout point; #221sets the auxiliary lockout point. See “Configuration,” p. 26.

Auxiliary Heat Control

Note: This feature applies only to the non-programmable 3-Heat/2-Cool thermostat.

You can set the auxiliary heat control using configuration option #17 to one of two settings:

• Comfort - prioritizes comfort over economy. Raising the temperature just a few degrees often will activate the auxiliary heat.

• Economy - attempts to reach the temperature setting without activating the auxiliary heat.

Economizer/TOD

Note: This feature applies only to the programmable thermostat.

You can set the Economizer orTOD mode using configuration option #150 to one of two settings:

• Economizer Mode - “A” terminal is energized with the thermostat in Occupied mode, Unoccupied mode with a call for cool, or aTimed Override mode (TOV) active.

• TOD Mode - “A” terminal is energized with thermostat in Occupied mode or aTimed Override mode (TOV) active.
